Sorry to be negative again, but I am not sure that thing would even go up the tracks in our wood. Walking to get to places, or taking a diesel tractor for extraction is the only way. I also can't see it doing much with the flints in some of the fields round here; would probably turn the thing over.

Still, might be nice for a bit of light market gardening on good soil.

I'm no farmer or scientist, but I'm wondering if an analogy can be made to the study into using hamsters to generate electricity......that is, the study came to the conclusion that it is more efficient to burn the hamster food to generate electricity, than to have hamsters running in a dynamo wheel.
A lot of energy must be lost propelling 140kg of tractor along.
I wonder, all things considered, whether a traditional wheel hoe is more effective and efficient.

A traditional wheel hoe is more effective IMHO, able to tackle more established weeds but slower & harder on the upper body. I've hoed an acre of fodder beet with a wheel hoe & it hurt. Give me the sit on my ass & pedal hoe anyday.
Does a pedalhoe float?

That pedal machine my be a thing of beauty and fairly carbon neutral, but I drove one with a massey T20 engine and removed most of the sugar beet I was supposed to be inter row cultivating (weeding). Put back to operate a hoe!
